N-Soliton Solutions for the Four-Potential Isopectral Ablowitz–Ladik Equation
-
Abstract
The bilinear form of the four-potential isospectral Ablowitz–Ladik (AL) equation is derived by the dependent variable transformation. The N-soliton solutions of the equation are obtained through the Hirota method. Moreover, the double Casoratian solution is found by means of the double Casoratian technique.
